• Integration is completed now. Activate the integration. Before submitting the integration, open the outlook email box and see the emails and attachments of each and every email. In my case, we have two emails, one has two attachments and another is having a single attachment. In total, there are three attachments

• Let’s submit the integration. After completion of the integration, open the SFTP location and notice the three files should exist there

This is how attachments can be fetched from outlook Inbox and save it to the SFTP location.
